I just need to vent

So it's been 2 years with my partner, we live together and emotionally we're inseparable. But it's also been about a year since I've had any sort of libido. I don't know what happened, it just went. Then when I do feel like sex, it's so painful I can't go through with it. I can feel the rift it's causing between me an my partner, even though he tells me he loves me and we'll get through this. I love him so much, and I do love sex I really do. I don't know what's happened to me. My GP has referred me for psychosexual therapy, but that was a month ago and I haven't heard anything. Chasing that up next week at my appointment, and I'm going to ask for antidepressants. I can't feel like this anymore.
